Garmin forerunner 45 turning off during run

My garmin forerunner 45 keeps turning off during a run. The watch is only 2 years old, has the most recent software version (5.40) and I have tried resetting it. Is there anything I can do about this?

Try deleting unneeded files from the watch over the US cable - old activities, workouts, courses, language files, etc. If it does not help, I suggest performing the master reset to factory defaults. If still no go, contact the Product Support.

The same thing happens to me when it is at 60% my battery goes off and when I turn it on I see 40% and when I go to charge it I see 60% again

Like trux mentioned, please reach out to your local Garmin Product Support team since your watch is up to date:

It is really annoying. The baterry pack is alway completely loaded before running. In the holidays in Costa Rei I alway run 10 -20 km and the watch doesn't work like I wish.

Good evening, the battery is to blame, I installed the previous software version and it turned off while the battery was at 60%

my mistake for the software version (it's 5.40) and it turned off while the battery was at 60%

I installed software version 5.00 ( downloaded beta software version 5.02 ) and gave it a test I was sure that it was software version 5.40

I must say that when i turn in clock mode, then all seems to be ok. Battery at 60% and works for 3-4 days. I think that the problem appears when i am in workout mode (running).

I have the same problem, and if you look at this related entry on the forum (https://forums.garmin.com/sports-fitness/running-multisport/f/forerunner-45-series/310828/it-turned-off-for-me), others clearly do too - 7 pages of people with similar issues. I would say it must be something to do with the latest software (or worse some built in obsolensence), but Garmin support don't seem interested - just suggested I return it and pay for a reconditioned one - but if it is software it will just happen again. Tempted to raise it with a consumer program such as You and Yours on Radio 4.
